Tpo all fui/tom z'tmay concern.' Be it known that I, CLA'roNE. BURKE, a

citizen of the UnitedStates, residingfV-'at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Mop Holders; and I do hereby declare the following to bea full, clear, and exact description of the invention, such afs will enable others skilled in thel artto which it appertains toma-ke and use the same.

My present invention is directed to the improvement of what is'known as mop holders andprovides an extremely simpley and highly etlicient device of this characterr Generally stated, 'the invention consists of the novel devices and comb-inations of deV` vices hereinafter described and defined in the claims. f

Holders of this character are, as is well known, designed to hold a mop clothor lrag' and must be adapted for quick application thereto and quick removal therefrom.

4The invention is illustrated in the ac companying drawings wherein Vlike characters indicate like parts throughout the several views. Referring to the drawings:

Fig. 1 vis a plan viewV showing the i1nproved holder, 'some parts being broken away;

Fig. 2 Fig. 1; Y

Fig. 8 is an enlarged section taken on the line 3 3 of Fig. 1; and`l l Fig. 4 is a transverse section takenon the line `4--4 of Fig. 1.v

The numeral 5 indicates an ordinary pole or handle, preferably of wood provided at its end with a ferrule 6. Secured to that end of the pole 5 is an approximately rectangular head frame 7, formed from a single piece of heavy wire bent to form prongs y y bottom of the channel; but when the threadthat are inserted into the pole.

The sides of the frame 7 are parallel and the transverse outer portion thereof, is advisedly covered with a tube 8 of rubber, or other 'suitable material.

Mounted to slide on the parallel side of the head frame 7 is a Vclamping head Vmade up of a metallic channel bar 9 in the guide yoke 10. The bar 9, as preferably -constructed, is of rolled metal bent to form a nearly complete rectangulartube, the'ends thereof being notched so that it is guided is a section ,on the line 22 of` byy the parallel'sides of the vsaid head?.l

Specification :if Letters Patent. `Pa1je1ted Fb. Application tied Nvemb'er 7,-1919. serial No. 336,381.

The vyokeA :10, is made 'from a piece'of wire bent to form a more or less complete 'elon-A gated loop, the outer portions of which embrace and slide onparallelsides of the head -frame 7;- The inturn'ed angesiof the bar '9 hold 'the guide loop v'10 loosely,-*but` securely in working positio`n,=so. that the complete clamping bar lisV securelygloeked .tothe sides of thehead7 but Y ree ,tol slideY thereon toward and from the Ytube 8.

For `forcing the movable clamping bar toward the 'co-operating, relatively fixed clampingy bar vmade up :of theftransverse portion of the head-7 and its covering tube 8, where `the latter is'pr'ovide'chjl provide a so-called vclamping strut that"4 is longitudinally adjustable," This 'strut'is'made up Y of a 'thrust1rod'11 threaded at one fendjand providednear its outer end withan'oifset vbend'gthat affords an 'operating crank vfor `rotating thesame.v The threaded end ofv the bolt or thrustjrod 11 works' with threadi' A ed'engagementthrough a nut'18 that is securely, but detachably' held 'inthe c'han'-y y nel-shaped outerportion 14 of an anchoring yoke 15, the prongsof which flatter vare l perforated, so that the 'slightly diverging inner portions of the head frame y7 yare passed therethrough. Thethrea'ded end of i' thefthru'st rod 1 1 works freelygthrough a perforation in what may be. treated as'the outervportion of Ithe-yoke' 15, or vthejbort.t c n`1 portion' of the channel 14.1 HerefV-itf should',l

be' noted that' theI channel 121 (see ,particular Fig. 3) hasinturned outerii'ange's that hold" the nut against displacement by movement in the direction of the extension of rod 11.

lVith this construction, therefore, the nut` 13 is held in the channel 14, when;- the threaded end of the bolt is extended through the nut and through the perforation in the outward of the vcrank 12, thrust rod 1l is provided with arigidly secured collar 16 thatafords a shoulder to'bear against the back of the movable clamping bar. The eX- treme outer end of the thrust rod'11 is invsertible through a perforation 17 formed in :is 1,407,123 A the central portion oi the back of the channel 9 of the movable clamping bar.

When the thrust rod 11 is turned so as to retract its outer end 'from the channel 9 of the movable clamping bar, and then turned to one side on the pivot afforded by the connection between the yoke 15 and head 7, then said clamping bar 9--10 may be freely slid bodily away from the fixed clamping bar of the head frame; and this, as is evident, permits the mop cloth not shown, but which may beef any well known form, to be readily inserted into position between the two clamping bars.

To clamp the mop cloth between the fined and movable clamping bars, it is then only necessary7 to press the movable clamping bar toward the ixed clamping bar as far as it will readilyy go by hand pressing, then to insert the outer end of the thrust rod 11 into the perforation 17 in the baclrof thel channel 9, and then, by turning the said rod,

yes

by manipulation of its crank 12, to tightly clamp vthe mop cloth between the two clamping bars. v. y y v :As is evident, the mop holder described is very simple and cheap construction.y lnactual practice, it has been found4 strong, durable andhighly eflicient for the purposes had in view. f

The novel connections between the rod 11 andbar 12 and between the nut 13 and yoke ,having parallel, sides and a transverse clamping bar, a movable clamping bar mounted to slide on the sides of said head y frame, and a displaceable axially extensible strut interposed Vbetween said movable clamping bar and head frame and having detachable engagement with said movable clamping bar.

2. A. mop holder comprising a head 'trame having iparallel sides and a transverse clamping bar, a movable clamping bar slidable on the sides of said head frame, an anchoring yoke pivoted on said head frame and provided with nut holding means, a nut held therein, and a thrust rod having at its inner end threaded engagement with said nut and provided near its outer end with a shoulder engaging with the back of said movable clamping bar, the extreme outer end ot said thrust rod being detachably insertible into a seat in said movable clamping bar. e f

3. A mop holder comprising a head frame having parallel sides and a transverse clamping bar, a movable clamping bar kslid-V able on the sides of said head trame, ananchoring yoke pivoted on said headirame and provided with a nut, and a thrust rod v having at its inner end threaded engagement kwith said nut and provided near its outer end with a shoulder engaging with the back `of said movable clamping bar, the extreme outer end ot said thrust rod being detachably insertible into a seat in said movable clamping bar, the said thrust rod also having an offset crank portion by meansoi' which it may be rotated. v

4.' The structure set forth in claim 2, said thrust rod being provided with means for rotating the same.

5. The structure set forth in claim 2, said nut holding means comprising outwardly 'formed flanges embracing the nut, said nut v being readily removable from between said flanges when disengaged from said thrust rod.

ln testimony whereof I ailix my signature Y in presence of two witnesses.
